Samsung Electronics is pouring more money into its gamble that folding smartphones will become the next big thing, as it projects a surge in sales of the novel handsets. Foldable smartphone sales are expected to increase by several times in 2021 from the previous year and continue significant growth in 2022, Samsung said on Thursday without providing a specific forecast. Its display division is expanding foldable panel production and making supplemental investments to pre-emptively address what the company sees as rising demand for the category. “We think that we have succeeded in starting and leading the mainstreaming of foldables in the market,” said Kim Sung-koo, a vice-president from Samsung’s mobile division during a conference call to discuss the company’s latest earnings on Thursday. The South Korean electronics giant launched the third-generation Galaxy Z Fold and Galaxy Z Flip in August, breaking new ground by pricing the smaller device at US$999 and promising to put the full force of its global marketing juggernaut behind the category. Powered by the Z Flip 3, the line-up sold a million units in South Korea at the fastest pace for any Samsung smartphone in two years, the company has said. Samsung is counting on the devices to lead the charge against Apple ’s perennial bestselling iPhone this holiday season. It skipped releasing a Note device this year and instead used its late-summer launch window to put the focus squarely on its foldable devices. The push into a novel smartphone form factor paid off for Samsung a decade ago when it introduced the Galaxy Note. It pioneered the larger screen sizes that have become common today and differentiated its devices with a unique stylus that has since also shown up in Apple’s iPads and Microsoft Corp ’s Surface devices. The Note series has reliably sold in the millions of units each year, but its distinctiveness has faded over the past decade. Samsung opted not to release a new model this year and decided to add a stylus to the Z Fold 3, making room for foldables to take over. The Note devices provide the blueprint for Samsung’s approach now: leading with hardware differentiation and comparable pricing to other top-tier smartphones. The Z series can cost more than US$1,800 – in line with the lofty pricing of foldable gadgets from all manufacturers to date – but Samsung moved to the sub-US$1,000 mark sooner than the competition with its Z Flip 3, which has expanded the potential customer base. How a Chinese manufacturing town found new life after Samsung’s departure Samsung has closed the gap between its foldable and regular smartphones, offering nearly identical specifications, including water resistance and 5G wireless support. The Flip can be used even while closed to make Samsung Pay contactless payments and it has a new, larger exterior screen that synchronises with the company’s Galaxy Watch. In testing by Bloomberg News , the device showed no signs of the durability flaws that plagued first-generation foldables from Samsung and others, though its comparatively small battery and overheating issues still need improvement. Samsung may also find it challenging to produce enough of the gadget to satisfy mass-market demand. Foldable smartphones are widely expected to become the fastest-growing phone category, with Counterpoint Research estimates pointing to 10-fold growth by 2023. Samsung may hold three-quarters of that market in the coming years, as it commands the supply of the most advanced foldable displays, the researchers said. Arch rival Apple has tested foldable iPhone prototypes, Bloomberg News previously reported, but none are imminent on the company’s product road map. Others like Xiaomi Corp and Oppo are still watching from the sidelines, while Motorola has found limited success with its foldable Moto Razr 5G .
